Abstract

This study was accomplished that analysis of seven polycyclic aromatic hydrocarbons (PAHs) in smoked or nonsmoked processing foods by high performance liquid chromatography (HPLC) with fluorescence detection. The calibration line was constructed with injected different levels of standard concentration. Limit of detection (LOD) and limit of quantification(LOQ) showed higher linearity ($r^{2}$=0.998) reasonably, and recovery exhibited 0.033-0.666 $\mu$g/kg, 0.108-2.217 $\mu$g/kg and 69.31-90.14%, respectively. As a result, the samples using smoked tuna as smoked materials contained seven PAHs with different range from 0.256 to 0.486 $\mu$g/kg. The benzo[a]pyrene, indicator of PAHs, was detected to below the LOQ in two samples. Concentrations of benzo[a]pyrene in three samples were below the 2 $\mu$g/kg which is the limit of regulation. Smoked tuna sauces were detected from 0.321 to 0.552 $\mu$g/kg and not detected in drying powders. PAHs of smoked meat products were ranged from 0.720 to 2.027 $\mu$g/kg and are higher than concentration of tuna smoked samples. PAHs were very low in non-smoked foods including mustard, herb, and roasted meats.

본 연구에서는 HPLC/FLD를 이용하여 훈연 처리한 가공식품과 조리용 소스류 12종과 훈연처리 하지 않은 일반 조리용 소스류 5종에 대해 발암성물질로 알려진 PAHs 함량을 조사하였다. 7 PAHs를 농도범위에서 측정했을 때 상관계수($R^{2}$)가 0.998이상으로 분석에 양호한 직선성을 나타냈으며, 검출한계는 0.033-0.666 $\mu$g/kg, 정량한계는 0.108-2.217 $\mu$g/kg, 회수율은 69.31-90.14% 으로 정성 정량분석에 만족할만한 결과를 얻었다. 분석결과 가다랑어 참치를 훈연재료로 이용하여 가공한 식품에서 7 PAHs 함량은 0.256-0.486 $\mu$g/kg으로 검출되었다. Marker PAHs로 알려진 benzo[a]pyrene의 경우 2개의 제품에서는 정량한계 이하로 검출되었고 3개의 제품에서는 각각 0.279, 0.288 및 0.308 $\mu$g/kg으로 검출되었지만 기준치인 2 $\mu$g/kg이하로 검출되었다. 가다랑어 참치를 훈연하여 제조한 소스류 중 엑기스 2종에서 7 PAHs 함량은 각각 0.321, 및 0.552 $\mu$g/kg으로 검출되었고, 분말소스 2종에서는 7 PAHs가 검출되지 않았다. 훈연과정을 거치치 않은 소스류를 대상으로 PAHs함량을 조사한 결과 겨자를 원료로 사용한 소스류 3종과 허브를 원료로 사용한 소스류 1종에서 7 PAHs가 검출되지 않았고, 숯불을 이용하여 제조한 불고기양념 소스류 1종에서 일부 PAHs가 검출되었지만 정량한계 이하였다. 육류를 훈연하여 제조한 육가공품에서 7 PAHs 함량은 0.720, 0.775, 2.027 $\mu$g/kg으로 검출되어 가다랑어 참치를 훈연하여 제조한 가공식품과 소스류보다 많은 함량이 검출되었다. 특히 발암성이 높은 benzo[a]pyrene이 0.542-1.803 $\mu$g/kg으로 검출되었으며, 일부 육가공품에서는 국내기준치(2 $\mu$g/kg)에 근접하는 결과값을 보였다.
